They didn't show it during their main show, but Ratchet and Clank: Crack in Time looks amazing.  I've been watching IGN's presentation of its demo and it looks much better than the first Ratchet and Clank Future.

Do you have a link?
I read this, but if there's a video, I wanna see it!

There is a video up on the PSN store Insomniac, developer talking points and everything.

go to this page http://e3.ign.com/, click on any of the three conferences, get to the next page, you might have to download the player, click on game demoes, and the first one in that list is ratchet and clank.

@ Torillian

Thanks, I was checking the PS store for a while there but it hadn't been updated so I figured I'd look some other time. Looks like I'll be headed to my PS3 now though. I'll edit this post with my thoughts when I get back. XD

EDIT: Looks great! I'm definitely a fan of that weapon they showed off, the one with the burping creature. I am hoping to see another weapon as epic as the Groovitron though...

I can't load the video page; every time I try, my browser crashes...
